Abstract

The invention discloses a method for extracting characteristic parameters of the hull shape line, which relates to the technical field of ships. The method can automatically extract the characteristic parameters of the hull shape line at a given draft by processing the ship shape file of the hull. When extracting, use different methods to extract according to the parameter types of each characteristic parameter, directly extract algebraic parameters such as scale and position, perform integral solution processing and extract integral parameters such as area and volume, and differentiate differential parameters such as angle and curvature Solving processing extraction, so that the characteristic parameters of three levels of the hull can be extracted: the global parameters representing the overall characteristics, the local parameters representing the regional characteristics, and the detailed parameters representing the detailed characteristics of the surface, which provide a data basis for subsequent data mining.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for extracting characteristic parameters of ship hull profiles. Background technique [0002] In the process of intelligent design of hull shape, it is necessary to extract valuable information from a large amount of data such as hull shape characteristics, flow field characteristics, and performance indicators, and carry out the next step of result analysis and data mining. Therefore, it is necessary to reasonably analyze and extract the characteristic parameters expressing the shape of the hull, but the characteristics of the shape of the hull are complex, and it is difficult to carry out deep data mining at present. Contents of the invention [0003] The present inventor proposes a method for extracting characteristic parameters of hull shape lines for the above-mentioned problems and technical requirements, and the method comprises the following steps: [0004] Obta...
